Magnet Dimensions

Magnetic Product Description:

These Neodymium Countersunk Magnets have a strong pull force and countersunk hole in the centre, making them one of the most versatile magnets in our stock. This Neodymium magnet is in a block shape with a countersunk 4-8mm hole in the centre. It has a 20mm length, 10mm height and a 4mm thickness, as well as a pull force of 3.5kg.

Uses for our rare earth block magnets:

This Neodymium Countersunk Block Magnet is a great tool for joining and holding due to the strong magnetic pull of the magnet as well as the countersunk hole in the centre of the block. This is a great all-purpose magnet that can be used to fasten or mount onto a surface or wall with a screw through the centre hole. It is axially magnetised through the 20mm length, meaning it can be fastened to a surface and the front can magnetise to an object or another surface. This small magnet has an impressive pull force in relation to its small size.

Customer Reviews
  1. Good but .....
    Magnets arrived very quickly but arrived with 2 cracked magnets in the centre of the pack. Attached the surviving magnets to the underside of a small key safe that can now solidly attach to the underneath of the car while parked.

    AMF Reply:
    Hi Stephanie, thank you for your feedback! Sorry to hear two magnets arrived cracked, we package all our magnets with a generous amount of bubblewrap to prevent any breakages during transit but if you'd like to send us email with a photo of the cracked magnets along with your invoice number we can arrange a replacement. Kind Regards, AMF Magnetics.
